Hmm, unfortunately, I can not as much English, maybe can someone translate it.

So these files are no more than pieces, the .efx is when you googel a fax file, which is something like script, about one can imagine, as in html, where is written is what happens and there is written : 1h_bld_06.ebm and will connect bld_light_green.ebs

The 1h_bld_06.ebm is only as a green frame, which can be seen on Osmium Blade, and the other file is the rest, so this bright

As if you wantot to change skills open this file and look what is written in it, there is usually something like Wi, Wa and so forth, so we can see what it is ^

I don't know whether you can change something with the hex editor, I had no need to read them out bares except scrap ^^

So simply said, osmium who can contribute, from his difficult is another weapon, as all other swords not have such effects, as Orbs, crystals, bows, swords and shields Osmium and so on.

The questions have no effect, because in order to make a Blade to a osmium Blade which would have to be something like a 1h_bld_00.efx gibs, and the net under EFX

Maybe someone finds out how to hack the file, so this cabal file loads, but you have to be the first to know which file is needed, these things efx invites ^^

Much fun when you try ^^ but instead here to make questions, go to level ^^ round then you have your weapon and osmium ne Mithrill makes it so easy XD weapon is the ^^ or her turns his Osmium Blade simply to the scythes XD looks only something strange in inventory ^^

Sry for the bad translation, but his german isn't really good, so it's hard to translate it :s
I used the google translation and a bit my english know-how, I hope you can understand it a bit.
